[Pharo-project] How do I know which issues are resolved in each new release?

Hi guys - I noticed there was a new 9.11.4 release since buenos aires - and I got to wondering what issues have been resolved in it (as I am trying to follow Pharo by example - I am trying to test out features to see if they work as I progress through the material). Anyway - is there a list of issues fixed marked against each new version? I can see the list at: http://code.google.com/p/pharo/issues/list# - but it doesn't list any build numbers - just milestone 1.1? Tim
